|discussion=<p>Reports of <i></i>subsp.<i> chamissonis</i> from Alaska or Yukon (E. Hultén 1968) have not been confirmed; they are unlikely.</p><!--
--><p>The current use of <i></i>subsp.<i> chamissonis</i> differs from that of J. Soják (1989, pers. comm.), who included <i>Potentilla</i> chamissonis among the hybrids of <i>P. arenosa</i> and <i>P. nivea</i>. He instead provided the combination <i>P. nivea</i> var. nipharga (Rydberg) Soják for the taxon currently under discussion, using <i>P. nivea</i> in its unconserved sense. He also noted, however, that P. nipharga Rydberg might instead be based on an unstabilized hybrid between <i>P. arenosa</i> and <i>P. crebridens</i> or <i>P. nivea</i>. The latter interpretation is provisionally accepted here; if treated as conspecific with <i>P. arenosa</i>, then P. nipharga would have priority. The name has traditionally been applied in Greenland and northeastern Canada; the type from the Mackenzie River does not conform with how the name has been used.</p>
